The correct answer is A.

In the 1st column, 2 X 1 + 1 = 3,

In the 2nd column, 12 X 9 + 9 = 117

Similarly, In the 3rd column, 7 X 14 + 7 = 105

Hence, the missing number is 7.

First option is wrong because a parallelogram is not always necessary to be a square or a rectangle ,as they only have diagonals equal. Second option is wrong because rectangle does not follow this property which can be checked by using SAS congruence criteria. Third option is wrong because if the diagonals of a quadrilateral intersect at right angles then it is necessarily a rhombus, if u are thinking that square also have this property then add up a point that every square is a rhombus. Fourth option is wrong because every quadrilateral is not necessarily be a trapezium, a parallelogram or a kite as concave quadrilaterals are none of them.
